3,033,437 PAINT ROLLER PAN Ehlert Wrage, 5110 W. Irving Park Road, Chicago, Ill. Filed Oct. 19, 1959, Ser. No. 847,190 2 Claims. (Cl. 229-34) The present invention relates to certain new and useful improvements in a disposable cardboard or an equivalent pan or tray which is expressly adapted to serve as a receptacle or container for paint and which lends itself to the practical utilization therewith of a paint applicator of the roller type.

An object of the invention is to structurally, functionally and otherwise improve upon similarly constructed and performing roller applicator pans and, having successfully done so, to advance this line of manufacture and use. It may be helpful for the reader to know that trays, receptacles and applicator pans for use in the home and elsewhere are of many and varied styles and forms. However and insofar as the instant invention is particularly concerned it may be said that the paint receptacle in the Serwer Patent 2,887,705 bears some resemblance to the instant subject matter in that it embodies a foldable cardboard or an equivalent disposable liner for use in a fabricated wire holder. By comparison the instant improvement has to do with a simplified construction which does not require a stand or a special holder but merely the cardboard or equivalent disposable tray, that is, a tray which is self-supporting and, more particularly, is constructed at one end that it may be conveniently fastened on the top step of a step-ladder or the like.

So far as has been ascertained it would appear that the state of the art to which the invention relates may perhaps be exemplified in the Faust Patent 2,444,096 covering a metal paint receptacle for use with roller type applicators. By comparison the instant invention is constructed of corrugated paper, it is comparatively inexpensive and because of this fact alone may be economically disposed of after nominal or limited use. In the prior patent a permanent metal pan and a particular attaching and retaining member is required.

Looking toward advancing the art and keeping in mind the state of the art exemplified in the two reference patents referred to, it is to be pointed out that in carrying out the invention the tray or pan is put out in stamped or cut-out form, that is, as a cardboard blank and the blank is so prefabricated and scored and otherwise marginally designed and constructed that the marginal portions may be fashioned into bendable walls defining a receptacle for the paint capable of accommodating a roller-type applicator. In addition, one wall at what may be called the forward end, is provided with hook-like attaching and retaining members.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying illustrative drawing.

In the drawing, wherein like numerals are employed to designate like parts throughout the views:

FIG. 1 is a view in perspective of a paint roller pan which is deep at one end and shallow at the other endand constructed in accordance with the invention and showing how it may be used on the top step of a ladder.

FIG. 2 is a section on the line 22 of FIG. 1 looking in the direction of the arrows.

FIG. 3 is a top plan view of the fiat cardboard blank from which the pan is bent up.

FIG. 4 is an enlarged view of the hook-on construction.

Although the finished ready-to-use pan or tray may be used by itself, that is, is self-supporting, it is also such that it lends itself particularly well to attachment to and use on the top step or platform of a ladder. The ladder is shown at A and the top step at B. The over-all usable pan or tray is denoted by the numeral 6. As before mentioned it is preferably of disposable stock and is also preferably stamped or cut-out from a single piece of corrugated cardboard. This is left in its flat condition until assembled by the painter or other user. Because the product is thus prepared and sold flat it may be easily handled and stacked so as to otherwise facilitate shipping and storage. The main bottom wall, which is flat at the top and bottom is denoted by the numeral 8 and this is a rectangular panel, as it were. The transverse end wall or flat at the left hand end in FIG. 3 is foldable on a score or fold line, as at 10 and when properly folded it becomes the upstanding back wall 12'. The side walls or side wall flaps are gradually tapered or narrowed in width and they are denoted by the numerals 14. The wider or higher end of each wall is denoted at 16 and the narrow end portion tapers to a point at 18. These side walls are foldable on the score lines 20. When they are folded up as shown the end fiaps 22 on the ends are bent inwardly and adhesively attached to the exterior surfaces of the back or rear wall 12. The transverse memher at the front end becomes a depending front wall24 and this is generally rectangular and is folded down on the line 26. In addition the end extensions 28 are foldable at right angles on the score or fold lines 30 and since these end portions are bifurcated the furcations serve in defining attaching hooks. The hooked portion is denoted at 32. Here again attaching and retaining flaps are provided and these flaps are generally trapezoidal in form and are denoted at 34. These flaps are bent in and adhere to the underneath side of the bottom in the manner shown perhaps best in FIG. 2. The flaps if desired may have pressure sensitive adhesive surfaces and these surfaces may be covered by removable seals 36. It follows that the rear wall 12' stands up along with the tapering side walls to define a receptacle which is deep at the left hand end and shallow at the right hand end. The depending front wall 24 becomes a prop and also provides attaching hooks or hooked attaching members 28 at the ends which may be engaged over an edge portion of the platform B of the ladder in the manner shown. The width of the wall 24 and the manner of constructing and attaching the hooks positions the tray or pan so that the inclination thereof is toward the deeper end to cause the paint to pool therein and to obviate the likelihood of spillage when the applicator roller (not shown) is brought into play.

It will be evident that the claims are directed to the cut-out pattern or blank and also to the complete readyto-use construction.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. For use in setting up and providing an on-the-spot disposable paint roller pan, a normally fiat cut-out blank of disposable cardboard embodying a fiat-faced body portion rectangular in plan and usable as a pan bottom, provided at a rearward transverse end with a rectangular end member constituting a back wall, said end member being joined to the body portion by a fold line, said blank being further provided along opposite longitudinal sides with side wall flaps joined to the body portion by parallel fold lines, said side wall flaps being gradually narrowed from their rearward toward their forward ends, said blank being provided at a front transverse end with a front wall joined to the body portion by a fold line and adapted to be bent downwardly at right angles to the plane of the body portion to constitute and provide a depending front wall, said front wall being provided at transverse ends thereof with end extensions bifurcated, said bifurcated portions defining furcations and said furcations defining and providing hooks, said bifurcated end extensions being provided on marginal portions with coplanar bendable attaching and retaining flaps having gummed surfaces adapted to be connected with an underneath side of the pan bottom.

2. For use in setting up and providing an on-the-spot disposable paint roller pan, a normally fiat cut-out blank of disposable cardboard embodying a fiat-faced body portion rectangular in plan and usable as a pan bottom, provided at a rearward transverse end with a rectangular end member constituting a back wall, said end member being joined to the body portion by a fold line, said blank being further provided along opposite longitudinal sides with side wall fiaps joined to the body portion by parallel fold lines, said side wall flaps being gradually narrowed from their rearward toward their forward ends, said blank being provided at a front transverse end with a front wall joined to the body portion by a fold line and adapted to be bent downwardly at right angles to the plane of the body portion to constitute and provide a depending front wall, said front wall being provided at transverse ends thereof with end extensions bifurcated, said bifurcated portions defining furcations and said furcations defining and providing hooks, each bifurcated end extension being provided on one marginal edge thereof with a substantially trapezoidal attaching and retaining flap, one marginal edge of the flap being joined by a fold line to the coperating marginal edge of the associated end extension, the other several marginal edges of said flap being free, one marginal edge being opposed to a cooperating marginal edge of the adjacent side wall flap, one surface of said attaching and retaining fiap having adhesive media whereby said surface may be attached to an intended underneath surface of the aforementioned body portion.
